The San Jose Mercury News reports ( http://bit.ly/UqflFq) the suspect—who has not been named—was shot as officers responded to 911 calls around 6 p.m. Saturday that a man was assaulting his mother.
Sunnyvale Public Safety Dept. Capt. Doug Moretto told the newspaper that when two officers arrived at the scene the suspect was standing in the street, then charged at the first officer with the hammer.
The officer fired several shots, hitting the man multiple times. The suspect underwent surgery Saturday night.
His condition was not known.
The last time there was an officer-involved shooting in Sunnyvale was in Sept. 2007 when two Sunnyvale officers shot and killed a 32-year-old man who was wanted on suspicion of murder.
